Trivia: This episode had a strong Dukes of Hazard theme as it reunited John Schneider (Jonathan Kent) and Tom Wopat (Senator Jack Jennings) who played Bo and Luke Duke respectively in the Dukes of Hazard. This included stunt driving by Jon Schneider, and him listening to "Good Ole Boys", the DoH theme song.
Trivia: Additional references to the show "The Dukes of Hazzard"; Senator Jennings (Tom Wopat) drives a '68 Dodge Charger, similar to the '69 Charger in DoH. Jennings mentions Jonathan outrunning cops when he was younger by driving through Chickasaw County, a fictional county in DoH the Dukes often weren't allowed to enter because of their probation, and were sometimes chased by the sheriff. And Jack Jennings' name is a nod to Waylon Jennings, who wrote the DoH theme song and was the Balladeer.
Trivia: This episode is a nod to "Buffy the Vampire Slayer." The episode was written by Steven DeKnight, who also wrote for and worked on the Buffy series and the spin-off "Angel." James Marster (who plays Milton Fine) starred in the Buffy series. The head vampire is name Buffy Sanders, a nod to Buffy Summers. We also learn that Buffy isn't the girl's real name but changed by Chloe in her story. At the end, Ms. Kahn says people don't want to read about "slaying Buffy the Vampire."
Answer: In the comics, Krypto is a dog from Krypton who was used as the passenger in a test launch by Jor-El, Superman's father, before he launched the actual rocket taking his infant son to Earth. Krypto's capsule was involved in a mishap, sending it out of Kryptonian orbit and eventually found its way to Earth where he linked up with the young Clark Kent. Like any native of Krypton, Krypto has superpowers on Earth. In Smallville, the dog is a standard Earth dog who has been experimentally injected with kryptonite, giving him super-strength for a limited period of time, who escapes and links up with Clark (who suggests the name Krypto, ostensibly because of the dog's cryptic origins). It doesn't take too long for the dog's strength to fade, and the Kents decide to keep him, although they ultimately name him Shelby, after a dog that Martha Kent had in childhood.
